Description
Electrical data
“Vin” Input (protected against undervoltage)
- 36 to 75V (accidental max.: 100V / 0.1s)
- no load consumption: 90mA to 100mA (see table on the PDF document)
- possible external fuse: 25A
- optional “ON/OFF” remote control
“Vout” Output
- 24V / 28V / 48V; accuracy: 1%
- optional fit with embedded “10 revolutions” axis: ±10%
- line and load regulation: < 2.10-3 of Vout
- temperature coefficient: 2.10-4 of Vout, per °C
- switching frequency: fixed (» 450 kHz)
- residual ripple: ≤1% of Vout
- nominal efficiency: 90% (losses ≤ 50W)
- dynamic response: 0.2 ms, with 25% load variation
- permissive capacitive load: 2,200µF to ≥ 22,000µF depending on load
Protections
- input-output insulation: 1500V DC. Internal filter on the input
- against overload and short circuit (even constant) by limitation
- in case of inductive load: option “L” will reinforce protection
- “inversion Vin” option: internal diode (external fuse required)
- abnormal temperature rise: automatic shutdown and restarting
- total sealing IP67
Thermal and environmental performances
- storage: -40 to +100°C; operating: -40 to +90°C
- cooling: natural convection (derating 2.5% per °C)
- temperature rise of the case, at full load: +50°C
- maximum ambient temperature at full power: 40°C for case 4 and 65°C for case 4S
- maximum ambient temperature at half power: 65°C for case 4 and 77°C for case 4S
- vibrations, shocks, humidity: protection by epoxy resin
